Business / Agriculture / Methane: A gas created by anaerobic decomposition of organic compounds. Natural gas is composed mostly of methane. Methane is a so-called greenhouse gas (see greenhouse effect). Agricultural wastes, especially animal wastes, are a major source of methane releases to the atmosphere.

Science / Chemistry / Dichloromethane: (CH2Cl2) Dichloromethane (CH2Cl2) is an organic solvent often use to extract organic substances from samples. It is toxic but much less so than chloroform or carbon tetrachloride, which were previousl MORE
Science / Chemistry / Combustion: A chemical reaction between a fuel and an oxidizing agent that produces heat (and usually, light). For example, the combustion of methane is represented as CH4(g) + 2 O2(g) = CO2(g) + 2 H2O(ell). MORE
Science / Chemistry / Methyl: A group -CH3, derived from methane. For example, CH3Cl is 'methyl chloride' (systematic name: chloromethane); CH3OH is 'methyl alcohol' (systematic name: methanol). MORE
